从原煤入选比例、选煤厂规模、选煤装备与工艺技术几个方面对比分析了国内外的煤炭洗选业发展情况。研究认为,与发达国家相比,我国选煤业起步晚、原煤入选率低、选煤装备现代化程度低。推动煤炭能源产业的可持续发展,还应高度重视选煤业的发展创新。 In this paper, the development of coal washing industry at home and abroad is comparatively analyzed from several aspects such as the proportion of raw coal, the size of coal preparation plant, the equipment of coal preparation and technology. The study shows that, compared with developed countries, China’s coal preparation industry started late, the selection of raw coal is low, the degree of modernization of coal preparation equipment is low. To promote the sustainable development of coal energy industry, should also attach great importance to the development of coal preparation industry innovation.
